These are all good reasons and true for me as well (I have a 5th floor walk up, need a light bike for that reason alone!).
Also, I might add that I wanted a bike that was good enough that I would not be riding around and seeing the other bikes, the bikes I could have had, constantly wishing I had the cool bike for a change. Buying the bike you want solves that problem
